COWBOY SNAKE is a game inspired by Snake game, that each player will control their own snake to eat food that appears around and fight with snakes controlled by other players around the world. Players only need to control their snake with the pointer and a click each time they want to speed up. Simple operation that anyone can play.
In addition to highly entertaining and training acumen for players, COWBOY SNAKE is also a game for you to collect for Snake Rinium (RIM), a type of Snake Gem encrypted as a Token on the Binance Smart Chain (BSC) platform. This is considered a reward for your contributions to the ecosystem. This model is called “Play To Earn”.

ERC20.transferToken(address,uint256,address) (ERC20.sol#515-524) ignores return value by IERC20(coinAddress).transfer(to,value) (ERC20.sol#523)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Reentrancy in COWSToken.constructor() (COWSToken.sol#15-23):
External calls:
- uniswapV2Pair = IUniswapV2Factory(_uniswapV2Router.factory()).createPair(address(this),_uniswapV2Router.WETH()) (COWSToken.sol#20-21)
State variables written after the call(s):
- uniswapV2Router = _uniswapV2Router (COWSToken.sol#22)
Apply the check-effects-interactions pattern.

Ownable.unlock() (Ownable.sol#84-89) uses timestamp for comparisons
Dangerous comparisons:
